Such a consistent formulation of a question deems a longer answer: you won't need multiple search patterns, you will only need one - and because you have already exactly specified what you need it is quite simple. Let us try:

OK: Note that not every grep understands "-w" but since you already used it i suppose yours does:

Code:

grep -w

Code:

grep -w '[0-9][0-9]*'

Code:

grep -w '[0-9][0-9]*-'

It is not clear what you mean by "words" here because it is definitely not the same meaning as you used above. I take it (from your example) that you mean sequences of capitalized characters, digits or hyphens, yes? If so:

Code:

grep -w '[0-9][0-9]*-[A-Z0-9-]*'

We need to escape the dot, because it has a special meaning to grep ("any character"):

Code:

grep -w '[0-9][0-9]*-[A-Z0-9-]*\.'

I hope this helps.
